phpDesigner error in connection to SFTP

[Rossere]

phpDesigner makes a mistake in connection:

Server does not support diffie-hellman-group1-sha1 for keyexchange

I've been trying to write a profile. sshd_config

kexalgorithms diffie-hellman-group1-sha1

The server doesn't even get involved.

What's the problem? WinSCP is well connected.

1. after application such as changes required /etc/ssh Keys:

   $ cd /etc/ssh
   $ sudo ssh-keygen -A
   

2. Here. https://www.veeam.com/kb2061 recommend the addition of other algorithms and ciphers- You, that's the line. kexalgorithms:

   kexalgorithms diffie-hellman-group1-sha1,curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1
   

   and another line ciphers:

   ciphers 3des-cbc,blowfish-cbc,aes128-cbc,aes128-ctr,aes256-ctr
   

3. And, of course, it's better to update this one. phpdesigner♪
